SYNOPSIS

DESCRIPTION

This tool is part of the samba(7) suite.
The Samba net utility is meant to work just like the net utility
available for windows and DOS. The first argument should be used to
specify the protocol to use when executing a certain command. ADS is
used for ActiveDirectory, RAP is using for old (Win9x/NT3) clients and
RPC can be used for NT4 and Windows 2000. If this argument is omitted,
net will try to determine it automatically. Not all commands are
available on all protocols.

OPTIONS

-h|--help
Print a summary of command line options.
-w target-workgroup
Sets target workgroup or domain. You have to specify either this
option or the IP address or the name of a server.
-W workgroup
Sets client workgroup or domain
-U user
User name to use
-I ip-address
IP address of target server to use. You have to specify either this
option or a target workgroup or a target server.
-p port
Port on the target server to connect to (usually 139 or 445).
Defaults to trying 445 first, then 139.
-n <primary NetBIOS name>
This option allows you to override the NetBIOS name that Samba uses
for itself. This is identical to setting the netbiosname parameter
in the smb.conf file. However, a command line setting will take
precedence over settings in smb.conf.
-s <configuration file>
The file specified contains the configuration details required by
the server. The information in this file includes server-specific
information such as what printcap file to use, as well as
descriptions of all the services that the server is to provide. See
smb.conf for more information. The default configuration file name
is determined at compile time.
-S server
Name of target server. You should specify either this option or a
target workgroup or a target IP address.
-l
When listing data, give more information on each item.
-P
Make queries to the external server using the machine account of
the local server.
-d|--debuglevel=level
level is an integer from 0 to 10. The default value if this
parameter is not specified is 0.
The higher this value, the more detail will be logged to the log
files about the activities of the server. At level 0, only critical
errors and serious warnings will be logged. Level 1 is a reasonable
level for day-to-day running - it generates a small amount of
information about operations carried out.
Levels above 1 will generate considerable amounts of log data, and
should only be used when investigating a problem. Levels above 3
are designed for use only by developers and generate HUGE amounts
of log data, most of which is extremely cryptic.
Note that specifying this parameter here will override the loglevel parameter in the smb.conf file.

COMMANDS

CHANGESECRETPW
This command allows the Samba machine account password to be set from
an external application to a machine account password that has already
been stored in Active Directory. DO NOT USE this command unless you
know exactly what you are doing. The use of this command requires that
the force flag (-f) be used also. There will be NO command prompt.
Whatever information is piped into stdin, either by typing at the
command line or otherwise, will be stored as the literal machine
password. Do NOT use this without care and attention as it will
overwrite a legitimate machine password without warning. YOU HAVE BEEN
WARNED.
TIME
The NET TIME command allows you to view the time on a remote server or
synchronise the time on the local server with the time on the remote
server.
TIME
Without any options, the NET TIME command displays the time on the
remote server.
TIMESYSTEM
Displays the time on the remote server in a format ready for /bin/date.
TIMESET
Tries to set the date and time of the local server to that on the
remote server using /bin/date.
TIMEZONE
Displays the timezone in hours from GMT on the remote computer.
[RPC|ADS]JOIN[TYPE][-Uusername[%password]][createupn=UPN][createcomputer=OU][options]
Join a domain. If the account already exists on the server, and [TYPE]
is MEMBER, the machine will attempt to join automatically. (Assuming
that the machine has been created in server manager) Otherwise, a
password will be prompted for, and a new account may be created.
[TYPE] may be PDC, BDC or MEMBER to specify the type of server joining
the domain.
[UPN] (ADS only) set the principalname attribute during the join. The
default format is host/netbiosname@REALM.
[OU] (ADS only) Precreate the computer account in a specific OU. The OU
string reads from top to bottom without RDNs, and is delimited by a
´/´. Please note that ´\´ is used for escape by both the shell and
ldap, so it may need to be doubled or quadrupled to pass through, and
it is not used as a delimiter.
[RPC]OLDJOIN[options]
Join a domain. Use the OLDJOIN option to join the domain using the old
style of domain joining - you need to create a trust account in server
manager first.

USERSHARE
Starting with version 3.0.23, a Samba server now supports the ability
for non-root users to add user-defined shares to be exported using the
"net usershare" commands.
Members of the UNIX group "sambashare" can create user-defined shares
on demand using the commands below.
The usershare commands are:
net usershare add sharename path [comment] [acl] [guest_ok=[y|n]] -
to add or change a user defined share.
net usershare delete sharename - to delete a user defined share.
net usershare info [-l|--long] [wildcard sharename] - to print info
about a user defined share.
net usershare list [-l|--long] [wildcard sharename] - to list user
defined shares.
USERSHAREADDsharenamepath[comment][acl][guest_ok=[y|n]]
Add or replace a new user defined share, with name "sharename".
"path" specifies the absolute pathname on the system to be exported.
Restrictions may be put on this, see the global smb.conf parameters:
"usershare owner only", "usershare prefix allow list", and "usershare
prefix deny list".
The optional "comment" parameter is the comment that will appear on the
share when browsed to by a client.
The optional "acl" field specifies which users have read and write
access to the entire share. Note that guest connections are not allowed
unless the smb.conf parameter "usershare allow guests" has been set.
The definition of a user defined share acl is: "user:permission", where
user is a valid username on the system and permission can be "F", "R",
or "D". "F" stands for "full permissions", ie. read and write
permissions. "D" stands for "deny" for a user, ie. prevent this user
from accessing this share. "R" stands for "read only", ie. only allow
read access to this share (no creation of new files or directories or
writing to files).
The default if no "acl" is given is "Everyone:R", which means any
authenticated user has read-only access.
The optional "guest_ok" has the same effect as the parameter of the
same name in smb.conf, in that it allows guest access to this user
defined share. This parameter is only allowed if the global parameter
"usershare allow guests" has been set to true in the smb.conf.
There is no separate command to modify an existing user defined share,
just use the "net usershare add [sharename]" command using the same
sharename as the one you wish to modify and specify the new options you
wish. The Samba smbd daemon notices user defined share modifications at
connect time so will see the change immediately, there is no need to
restart smbd on adding, deleting or changing a user defined share.
USERSHAREDELETEsharename
Deletes the user defined share by name. The Samba smbd daemon
immediately notices this change, although it will not disconnect any
users currently connected to the deleted share.
USERSHAREINFO[-l|--long][wildcardsharename]
Get info on user defined shares owned by the current user matching the
given pattern, or all users.
net usershare info on its own dumps out info on the user defined shares
that were created by the current user, or restricts them to share names
that match the given wildcard pattern (´*´ matches one or more
characters, ´?´ matches only one character). If the ´-l´ or ´--long´
option is also given, it prints out info on user defined shares created
by other users.
The information given about a share looks like: [foobar]
path=/home/jeremy comment=testme usershare_acl=Everyone:F guest_ok=n
And is a list of the current settings of the user defined share that
can be modified by the "net usershare add" command.
USERSHARELIST[-l|--long]wildcardsharename
List all the user defined shares owned by the current user matching the
given pattern, or all users.
net usershare list on its own list out the names of the user defined
shares that were created by the current user, or restricts the list to
share names that match the given wildcard pattern (´*´ matches one or
more characters, ´?´ matches only one character). If the ´-l´ or
´--long´ option is also given, it includes the names of user defined
shares created by other users.
CONF
Starting with version 3.2.0, a Samba server can be configured by data
stored in registry. This configuration data can be edited with the new
"net conf" commands.
The deployment of this configuration data can be activated in two
levels from the smb.conf file: Share definitions from registry are
activated by setting registryshares to “yes” in the [global] section
and global configuration options are activated by setting include=registry in the [global] section for a mixed configuration or by
setting configbackend=registry in the [global] section for a
registry-only configuration. See the smb.conf(5) manpage for details.
The conf commands are:
net conf list - Dump the complete configuration in smb.conf like
format.
net conf import - Import configuration from file in smb.conf
format.
net conf listshares - List the registry shares.
net conf drop - Delete the complete configuration from registry.
net conf showshare - Show the definition of a registry share.
net conf addshare - Create a new registry share.
net conf delshare - Delete a registry share.
net conf setparm - Store a parameter.
net conf getparm - Retrieve the value of a parameter.
net conf delparm - Delete a parameter.
net conf getincludes - Show the includes of a share definition.
net conf setincludes - Set includes for a share.
net conf delincludes - Delete includes from a share definition.
CONFLIST
Print the configuration data stored in the registry in a smb.conf-like
format to standard output.
CONFIMPORT[--test|-T]filename[section]
This command imports configuration from a file in smb.conf format. If a
section encountered in the input file is present in registry, its
contents is replaced. Sections of registry configuration that have no
counterpart in the input file are not affected. If you want to delete
these, you will have to use the "net conf drop" or "net conf delshare"
commands. Optionally, a section may be specified to restrict the effect
of the import command to that specific section. A test mode is enabled
by specifying the parameter "-T" on the commandline. In test mode, no
changes are made to the registry, and the resulting configuration is
printed to standard output instead.
CONFLISTSHARES
List the names of the shares defined in registry.
CONFDROP
Delete the complete configuration data from registry.
CONFSHOWSHAREsharename
Show the definition of the share or section specified. It is valid to
specify "global" as sharename to retrieve the global configuration
options from registry.
CONFADDSHAREsharenamepath[writeable={y|N}[guest_ok={y|N}[comment]]]
Create a new share definition in registry. The sharename and path have
to be given. The share name may not be "global". Optionally, values for
the very common options "writeable", "guest ok" and a "comment" may be
specified. The same result may be obtained by a sequence of "net conf
setparm" commands.
CONFDELSHAREsharename
Delete a share definition from registry.
CONFSETPARMsectionparametervalue
Store a parameter in registry. The section may be global or a
sharename. The section is created if it does not exist yet.
CONFGETPARMsectionparameter
Show a parameter stored in registry.
CONFDELPARMsectionparameter
Delete a parameter stored in registry.
CONFGETINCLUDESsection
Get the list of includes for the provided section (global or share).
Note that due to the nature of the registry database and the nature of
include directives, the includes need special treatment: Parameters are
stored in registry by the parameter name as valuename, so there is only
ever one instance of a parameter per share. Also, a specific order like
in a text file is not guaranteed. For all real parameters, this is
perfectly ok, but the include directive is rather a meta parameter, for
which, in the smb.conf text file, the place where it is specified
between the other parameters is very important. This can not be
achieved by the simple registry smbconf data model, so there is one
ordered list of includes per share, and this list is evaluated after
all the parameters of the share.
Further note that currently, only files can be included from registry
configuration. In the future, there will be the ability to include
configuration data from other registry keys.
CONFSETINCLUDESsection[filename]+
Set the list of includes for the provided section (global or share) to
the given list of one or more filenames. The filenames may contain the
usual smb.conf macros like %I.
CONFDELINCLUDESsection
Delete the list of includes from the provided section (global or
share).
HELP[COMMAND]
Gives usage information for the specified command.
